\left(4x-5\right)\times 15=\left(2x-3\right)\times 19
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara \frac{5}{4},\frac{3}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(2x-3\right)\left(4x-5\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2x-3,4x-5.
60x-75=\left(2x-3\right)\times 19
Whakamahia te āhuatanga tohatoha hei whakarea te 4x-5 ki te 15.
60x-75=38x-57
Whakamahia te āhuatanga tohatoha hei whakarea te 2x-3 ki te 19.
60x-75-38x=-57
Tangohia te 38x mai i ngā taha e rua.
22x-75=-57
Pahekotia te 60x me -38x, ka 22x.
22x=-57+75
Me tāpiri te 75 ki ngā taha e rua.
22x=18
Tāpirihia te -57 ki te 75, ka 18.
x=\frac{18}{22}
Whakawehea ngā taha e rua ki te 22.
x=\frac{9}{11}
Whakahekea te hautanga \frac{18}{22} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
